WASHINGTON – House Democrats are broadening the scope of their investigations into President Trump and those closest to him, sending new demands to scores of people close to the president including his children, former business associates, and administration officials.

Monday morning, the House Judiciary Committee officially launched the sweeping new probe against Trump, demanding documents from 81 people.

House Judiciary Chairman Rep. Jerry Nadler (D-NY) said Sunday on ABC's "This Week With George Stephanopoulos" that it's too early to talk about impeachment but he does believe Trump obstructed justice.

"Over the last several years, President Trump has evaded accountability for his near-daily attacks on our basic legal, ethical, and constitutional rules and norms," Nadler claimed Monday.

House Minority Leader Kevin McCarthy ( R-CA) insists Nadler's sights have always been set on impeachment.

"I think Congressman Nadler decided to impeach the President the day the President won the election," McCarthy told Jake Tapper Sunday on CNN's "State of the Union."

There are now six committees investigating President Trump for alleged collusion with Russia in the 2016 election, his tax returns, and possible conflicts of interests in his business dealings. Nadler says the committees will use all legal means necessary to get the information they're seeking.

Trump says these new investigations are coming because Special Counsel Robert Mueller's probe isn't panning out.

"There is no collusion," Trump said Saturday in a speech to CPAC (Conservative Political Action Conference). "So now they go and morph into, 'Let's inspect every deal he's ever done'."

This all comes after Trump's former personal attorney Michael Cohen's blistering testimony before Congress last week. Nadler says it opened up several new avenues.

Trump believes holding the hearings at the same time as the Hanoi summit weakened him in negotiations with Kim Jong Un.

"For the Democrats to interview in open hearings a convicted liar & fraudster, at the same time as the very important Nuclear Summit with North Korea, is perhaps a new low in American politics and may have contributed to the 'walk.'" Trump tweeted Sunday. "Never done when a president is overseas. Shame!"

On top of the investigations, there's more bad news for President Trump this week. GOP Sen. Rand Paul (R-KY) will join three other Republicans for a resolution blocking Trump's emergency declaration to build a border wall, giving it enough votes to pass the Senate. It passed the House last week. Trump is expected to veto the resolution.
